| 38 | // A G4Cons is, in the general case, a Phi segment of a cone, with
|
|---|
| 39 | // half-length fDz, inner and outer radii specified at -fDz and +fDz.
|
|---|
| 40 | // The Phi segment is described by a starting fSPhi angle, and the
|
|---|
| 41 | // +fDPhi delta angle for the shape.
|
|---|
| 42 | // If the delta angle is >=2*pi, the shape is treated as continuous
|
|---|
| 43 | // in Phi

|
|---|
| 50 | // fRmax2 outside radius at +fDz

| 58 | // Note:
|

| 59 | // Internally fSPhi & fDPhi are adjusted so that fDPhi<=2PI,
|
|---|
| 60 | // and fDPhi+fSPhi<=2PI. This enables simpler comparisons to be
